To add a resource to the registry instance, create a Resource object and then call its put method:
1. Create a collection called "/c1/c2."
Collection collection = registry.newCollection();
2. Call the put method.
registry.put("/c1/c2", collection);
If you call the get method, then you will be able to access that created resource.
To add a resource with content, create a Resource object and then set content.
Resource r1 = registry.newResource();
String str = "My File Content";
r1.setContent(str.getBytes());
registry.put("/c1/c2/r1", r1);
